Audio too loud on my MacBook Air!
So, I just purchased my MacBook Air from Best Buy (as an Open Item since there was an awesome markdown plus coupon markdown on top of that, and 18 months financing is pretty cool too). My problem is that the sound is extremely loud on this system, especially when I have headphones plugged in. I have the master volume at the 4-5 level (out of 16, mind you), and headphones can only be set on 1 (or if using the gradual shift with Shift+Option+Vol Up/Down it would be more like .5). If I have it set to full volume, the speakers are blaring (and I'm sure I'd be permanently deaf if I tried that with headphones on). This is my first Apple laptop, and I don't have this issue with my iMac (but I've got a pretty decent set of external speakers hooked up to that, so if there is an issue I don't notice it).
I tried fiddling with the sound in the System Preferences, but all I have access to is the Alert Volume slider and the Output Volume slider (which I found is the same as using the volume hot keys). And for the Output preferences tab, I can select the headphones, but all it gives me is a balance slider, no individual volume control for them.
I've been googling and searching this issue in this Support Forum, but most of what I'm finding is about the system having the opposite problem (extremely low audio), and the few that seem to have the same problem as I do aren't really getting a definitive answer. I thought I saw one where somebody had this problem and took it into an Apple store, where they popped the laptop open and noticed that something wasn't hooked up correctly (wires hooked up wrong, or something like that). But I can't find that particular thread anymore, so I'm a bit uncertain on that - anybody know where that thread is and can I have a link?
I'm wondering if this particular MacBook Air was returned because of this sound issue. Should I take my MacBook Air in to get it looked at? And if so, should I just go into a full Apple store rather than the Geek Squad (which is more PC oriented)? I did purchase a Geek Squad Black Tie plan, mostly for the accidental coverage. (I'm a klutz).
